The Occupational Safety and Health Administration (OSHA) requires all Postal Service™ installation and establishment heads to prepare and post the OSHA Form 300A, Summary of Work-Related Injuries and Illnesses, for calendar year (CY) 2012, in accordance with 29 CFR 1904 and the Employee and Labor Relations Manual (ELM) 821, Actions in the Event of Accident, Injury, or Illness.
From February 1, 2013 through April 30, 2013, installations are required to post a copy of the OSHA 300A for CY 2012 in a conspicuous place at every establishment where employees work or report to work.
Before posting and signing, the installation or establishment heads are required to review the OSHA 300 Log and the OSHA 300A Summary Reports. When they sign the OSHA 300A, they are affirming that they have reviewed both OSHA forms for accuracy and completeness (whether they use manual or automated versions).
When the OSHA 300 Log is reviewed, installation heads must pay close attention to column F. This includes describing the injury or illness, the parts of the body affected (including which side of the body), and the object or substance that directly injured or made the person ill (for example: “second degree burns on right forearm from acetylene torch”).
Installation heads must also pay close attention to columns K and L. If an injury is identified as “days away from work” in column K or “on the job transfer or restriction” in column L, the installation head must ensure that the number of days entered is accurate.
For every entry on the OSHA 300 Log, the installation head must ensure that there is a corresponding Accident Report Form 1769/301 in the Employee Health and Safety (also known as EHS) application; which populates the OSHA 301, Injury and Illness Incident Report.
The left side of OSHA 300A contains sets of information data points, with a letter (such as K) corresponding to each data point. The data points come from the OSHA 300 Log summary columns with the same letter. The right side of the OSHA 300A form is self-explanatory except for the North American Industrial Classification (NAICS) code. The code for Vehicle Maintenance Facilities is 8111; the code for all other Postal Service establishments is 4921.
